Underground FRP water tank is a new type of water storage equipment specially designed for underground burial, using double-layer hand lay-up molding process, with food-grade resin inner layer and high-strength structural outer layer.

【Advantages】Compared to traditional concrete tanks: faster installation (2-3 days), no leakage, no waterproofing required, lower maintenance costs. Compared to metal tanks: stronger corrosion resistance, longer service life (30+ years).

【Structure Design】Shell: high-strength FRP laminate; Inner lining: food-grade resin coating; Outer anti-corrosion: epoxy asphalt coating (thickness ≥1.5mm); Rib spacing: 0.5m; Maximum burial depth: 3.0m.

【Specifications】Capacity: 5-500m³; Diameter: DN1000-DN4000; Length: 2-15m (customized); Working temperature: 0°C to +40°C; Standard: GB/T21238.
